QXN.water охлаждение встроенным погружного насоса

General Introduction to Products: QXN water-cooling built-in submerged pump consists of three components, water pump, sealing and electrical motor.The motor is of dry type,mounted on top of pump and divided into single phase and three-phase asynchronized versions .Double-face mechanic sealing is mountedbetween pump and motor. O shaped oil-proof rubber sealing ring is used at each stationary port as static sealing . This series features high delivery,new and unique structure. The waterit delivers flows around the motor at high speed and effectively cool the motor, therefore,the reliability and life time of the motor are improved. Conditions: The pumps can operate properly and continuously under following operation conditions: 1.Working medium carries no corrosives,sand contents shall be max.0.10% by volume and granular size shall be max.0.20mm. 2.Medium temperature shall be 40°C and PH shall be 6.5-8.5. 3.The pumps shall operate within the nominal delivery rangesubmerged depth of less max.depth of 5m. 4.Power frequency shall be 50HZ,three-phase voltage 380V and voltage fluctuation shall be 0.9-1.1 times the nominal.
